Abstract (en)
A method and system for transferring electronic image data to film which provides correlation or matching between an image as viewed on a video monitor (14) and an image viewed on film. Apparatus (20) is disclosed for measuring image intensity on a video monitor and converting the measured intensity to electronic signals. The image intensity on film under controlled lighting is measured (28) and signals representative of film density provided. The signals obtained by the two measurements are compared (32) and any difference is used to vary (22) a film writing system in a manner to minimize the difference.
